Answer:
look below 
Step-by-step explanation:
thing to note: 
sin = opposite/hypotenuse 
cos = adjacent/hypotenuse 
tan = opposite/adjacent 
opposite= side across angle you are using 
hypotenuse= side across 90 degree angle 
adjacent= remaining side 
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6
hope that helped. let me know if you have any questions:)

Answer:  x = 7
`Step-by-step explanation:
Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:
  9 cm       72 cm
----------- = -----------
 3x - 20      56 cm
Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²
Dividing both sides by 72 cm, we get:
3x - 20 = (504 cm²) / (72 cm) = 7
Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.
